SPECIFICATION forming part of Letters Patent No. 739,074, dated September 15, 1903. Application filed December 8, 1902. Serial No. 134,421. (No model.)

To all whom, it mctycorwern:

Be it known Ithat I, GEORGE GIBBs, a citizen of the United States, and a resident of New York, in the county of New York and State of NewYork, have invented certain new and useful Improvements in Railway-Vehicles, of which the following is a specification.

One of the objects of my invention is to provide a railway passenger-car, more particularly an electric-motor car, which shall be little likely to take fire in case of accident or the derangement of the electrical apparatus. To this end I make the frame of the car ot' metal and provide the car with a non-metal-A lic non-splintering lining, said lining being either entirely noncombustible or of slowburning composition. Such a lining serves also the additional function of deadening sound and provides a heat-and-cold-insulatf ing partition, providing in Athis respect the requisite comfort for passengers in the car. An all-metal car would not fulfil these f unc-` tions, and such a car would also be objectionable for use in connection with the electrical apparatus by reason of the danger of short circuits burning through the metal and causing alarm and possibly injury to the passengers. Accordingly, a second Object of my invention is to equip a metal car with a nonmetallic lining, not only for purposes of making the car fireproof, but also for securing the passengers against the extreme eects of heat and cold which would be present in-an unlined metallic car and for deadening the sound which an all-metal car would transmit to the interior of the car. In electric-motor cars the dangers from electrical apparatus in respect to the causing of tires may be divided, broadly, into two classes: first, that arising from defects in the apparatus when in normal operation; second, that arising from short circuits, grounds, duc., in case of derailment, wreck, or any serious accident.

In another application for Letters Patent,

filed on the lst day of December, 1902, Serial No. 133,313, I have suggested as a means for providing against the iirst class of danger the mounting of the electrical apparatus, including the wiring, under the floor of the car and making the door-lining of fireproof construction, an air-space being preferably provided between the electrical apparatus, including the wiring, and the car-body. This mode of protection will generally be found effective; but incase of the more serious forms of railway accident it is always possible that short circuits will occur between feeders or collector-rails and the ironwork on the track or car, thus endangering the woodwork of the car when a car having wood in its construc- :tion is used. This danger of short circuits and of the exposure of the non-metallic portions of a metal car to electric arcs extends to the lining of such cars whether such lining is of wood or other material. Aspecial danger connected with the use Of wood as a lining for a metal car arises from the splintering of the wood, whereby the danger of lire is greatly increased. I propose a new form of construction in which the car has an allmetal frame above the floor, with a metallic outside sheathing, but with a lining of nonsplintering board composition, made either of Wood-pulp fiber, preferably impregnated with metallic salts to make it nonfiammable, or of composite board made of woodpulp and asbestos or other non-combustible compositions capable of being formed into board of the requisite mechanical strength and toughness. When the principle of construction which I have developed is broadly considered, the exact composition of this 1ining is comparatively unimportant, so long as the necessary qualities of mechanical strength and non-fiammability and the characteristic of permitting distortion by bending instead of breaking or splintering are present.

In the accompanying illustrative drawings, Figure l is an outside elevation of aportion of a railway passenger-car embodying my invention. Fig. 2 is aninside elevation of the same.

Fig. 3 is a cross-section of one-half of the can'4 body.v Fig. 4 is an enlarged detail View of the roof portion of Fig. 3. Fig. 5 is an enlarged detail view of the roof corner construction between windows. Fig. 6 is a horizontal section through a window-post in the car-frame. Fig. 7 is a horizontal section through a post in the car-frame, taken on a plane below the car-window. Fig. 8 illustrates a modification of the construction shown in Fig. 7, and Fig. 9 is a view showing electrical car apparatus and Wiring arranged underneath the floor of the car.

IOO

The floor-framing, as shown in Figs. 1, 2, and 3, may consist of angle side sills 1, channel center sills 2, running longitudinally of the car, and transverse angular bridge-pieces 3, these parts being of metal. Any other suitable metallic framing.r for the floor may be employed. The tireproofing and insulation of the lioor may be formed by a board 4, of transite or similar iireproong material, laid on top of the bridge-pieces 3. On top of the sills is laid a iiooring 5, of sheet metal, which may be in the form of a corrugated sheet, and on top of this is placed a plastic ooring 30, of asbestos, magnesia composition, or other suitable material forming the door-surface.

The side framing of the car is preferably formed of posts 6 6, of Z-iron, although they may be of other structural shapes, if found desirable. These Z-irons extend from the footing in the side angle 1 to a side roof-angle 7, being properly secured to the same by bolting or riveting or any other suitable means. The posts 6 6 form the vertical frame between the side windows and are so secured lo the outside sheet-sheathing 8, of metal, (see Figs. 1, 3, 5, and 8,) as to form a vertical truss. The sheathing 8 is riveted to the posts 6 6 and extends from the bottom of the side sill1 to a window-sill angle-piece 9 9. Around these posts between the windows finishing-strips 10 l0, of pressed metal, are secured. (See Fig. 6.) This finish is preferably made so as to hold the window-sash 1l in place and is secured by screws 12 12 to the window-frame castings 13 13. These strips 10 10 are preferably formed so as to exert a spring-pressure when screwed in place, and thus to hold the sash from rattling.

The roof construction is formed of the metallic carlines 14 14, extending from one side of the car to the other'. and placed at the proper intervals for roof strength. The longitudinal frame between these carlines consists of angle-pieces 15 15, these angle-pieces being properly bolted, riveted, or otherwise secured to the carlines where they join or The outside roofing may be meet the same.

of sheet metal or of the non-metallic lining material where lightness is desirable and is secured by bolting, riveting, or other means to the longitudinal roof angle-pieces 15 15.

The interior lining 17 consists of non-metallic non-splintering lining material below the window-sills and between and above the windows. This lining is secured to the posts by one of several alternative methods, exaluples of which are shown in Figs. 7 and S. In Fig. 7 it is screwed or bolted directly to the Z-posts. In Fig.'8 the liningis held in place by vertical strips 18 18, preferably of metal, which are held in place by the T-bolts 19. The roof-lining consists of non-metallic sheets 20, bolted to the carlines 14 and secured by corner finish-strips 2l 21,-as necessary.

In Fig. 9 I show a car, which may be of the general construction hereinbefore described, such car being provided with electrical apparatus arranged underneath the floor. Thus I show in the said figure resistances 22, supported in a frame 23, the frame being bolted or otherwise secured to the bottom of the car, either directly or indirectly. At 24 24 I indicate the motors,which are supported upon the trucks 25 25. The part 2G is a typical representation of a controller, and the wiring is indicated at 27.

I claim as my invention- An electric-motor ear having a frame of metal,a metallic outside sheathing,and an exposed lining ot' insulating, non-splintering, sound-deadening, non-combustible, or slowburning material, in combination with electric motors suspended on the trucks and electrical controlling apparatus for the said motors, the major portion of the said controlling apparatus beinglocated under the car-bottom.

Signed at New York, in the county of New York and State of New York, this 6th day of December, A. D. 1002.
